Sophos UTM Identify and Stop VPN usage

[Theldron]

Hi all,

 

I have been asked to look at blocking all VPNs going through our firewall by students, on their devices through the Sophos UTM. Is this possible and how would I go about it?

 

Cheers

If this is UTM (not XG) First turn on "Network Visibility" under Web Protection > Application Control

Then add a New Rule on the Application Control tab, just add in the application(s) you want to block.

 

You can get away with a measure of control if HTTPS inspection isn't covering the clients.

 

You can check on application usage under the Logging & Reporting > Network Usage > Bandwidth Usage tab and change the view to Top Applications.

cheers
